I'm not aware of any evidence that C++ Lifetimes will detect "most misuse". It will detect some common lifetime errors. It will certainly fail to detect other common lifetime errors. https://robert.ocallahan.org/2018/09/more-realistic-goals-for-c-lifetimes-10.html https://robert.ocallahan.org/2018/09/more-realistic-goals-fo... Since it fails to detect common lifetime errors, it's not surprising it's more "flexible" than Rust NLL, which prevents all lifetime errors.
